I`m looking to fit a towbar to my 2007 A4 Avant 2.0Tdi, does anyone know
what the colour code is for the CAN system?
If you are fitting vehicle specific electronics, it should just plug in to the appropriate socket. And coding with vcds.

I am fitting a Towequipe towbar and the instructions for the car specific relay suggest that it should be connected to the CANBUS wires coming from the ignition using `Scotchblocks`! just needed to confirm the colours for the CAN system?

See this thread I posted for some pointers. I still haven't located the source of the pdf which I followed to do the job.
Towbar electrics help (http://www.vwaudiforum.co.uk/forum/showthread.php?100605-Towbar-electrics-help&highlight=towbar)
I'd rate this as definitely more than an afternoon's tinkering. Put plenty of time aside to do a nice job.

The excellent pdf guide has a link in this thread: http://www.vwaudiforum.co.uk/forum/showthread.php?85521-quot-How-To-quot-remove-the-rear-bumper-off-an-A4-B7-Avant-S-line-and-fit-a-removable-tow-bar-and-reversing-sensors (go to post number 21).
Sadly it no longer works. I have a copy but not sure if I can post it as it is someone elses hard work. Could mail it if anyone is really interested.
